Help with an assessment of a 5513 Maxi Dial

Hi,
I would hugely appreciate the thoughts and comments from those in the know here on this 5513 I am considering.
I believe the dial is known as pre Comex which is correct for the serial number of The serial number is and it has a pre comex dial which I believe to be correct as it has a serial number 589XXXX, the tritium on hands and dial match well. The case looks very good to me, neither overly polished or recently recut and the crystal looks original. But what I cannot work out is the bezel insert, it is trapezius in the 40 and the 40 has a serif on the horizontal bar but this does not seem to match others for sale of this era. It appears to be in good condition though also glossy which leaves me with some doubts.
It would be great if those with more experience could give me their input

Thanks ATWG, it was from the 5513mattedial site where I learned it was a pre-comex dial, is there something else you think I have missed? But it doe say very little about bezels.
Cheers
Shaun

Insert is later and case is a bit over polished, as correctly stated.

I would add that the dial is a bit earlier compared to the serial, you can usually find Precomex dial in early the 5 mil serial number.

Thank you for the input everyone, I have no background on the seller, it is not from a known dealer and you are right the photo’s do look professional.

I did not pick up on the case, I thought it looked quite thick and strong, not looking close enough at the crown guards I guess.

Was thinking of offering US$15k max, not sure if it is actually worth going that high?

Thanks, that is awesome, I was using the write up from watchprosite which is good but is more detailed on the earlier versions.
